IMPORTANT NOTICE
IMPORTANT NOTICE
•
This dealer's manual is intended primarily for use by professional bicycle mechanics.
Users who are not professionally trained for bicycle assembly should not attempt to install the components themselves using the dealer's manuals.
If any part of the information on the manual is unclear to you, do not proceed with the installation. Instead, contact your place of purchase or a local
bicycle dealer for their assistance.
•
Make sure to read all instruction manuals included with the product.
•
Do not disassemble or modify the product other than as stated in the information contained in this dealer's manual.
•
All dealer's manuals and instruction manuals can be viewed on-line on our website (http://si.shimano.com).
•
Please observe the appropriate rules and regulations of the country, state or region in which you conduct your business as a dealer.
For safety, be sure to read this dealer's manual thoroughly before use, and follow it for correct use.
The following instructions must be observed at all times in order to prevent personal injury and physical damage to equipment and surroundings.
The instructions are classified according to the degree of danger or damage which may occur if the product is used incorrectly.

CAUTION
Failure to follow the instructions could cause personal injury or physical damage to equipment and surroundings.

TO ENSURE SAFETY
TO ENSURE SAFETY
WARNING
•
Be sure to follow the instructions provided in the manuals when installing the product.
It is recommended to use genuine Shimano parts only. If parts such as bolts and nuts become loose or damaged, the bicycle may suddenly fall over,
which may cause serious injury.
In addition, if adjustments are not carried out correctly, problems may occur, and the bicycle may suddenly fall over, which may cause serious injury.
•
Be sure to wear safety glasses or goggles to protect your eyes while performing maintenance tasks such as replacing parts.
•
After reading the dealer's manual thoroughly, keep it in a safe place for later reference.
Be sure to also inform users of the following:
•
Check that the wheels are fastened securely before riding the bicycle. If the wheels are loose in any way, they may come off the bicycle and serious
injury may result.
•
This wheel set is designed for recreational use. Do not use this wheel set for aggressive uses such as competition.
•
Before use, check the wheels to make sure that there are no bent or loose spokes, dents, scratches or cracks on the rim surface; do not use the wheel if
any of these problems are found. The wheel may break, and you may fall.
•
If the quick release mechanism is not used correctly, the wheel may come off the bicycle and serious injury could result. Read the Service Instructions
for the quick release mechanism thoroughly before use.
•
These wheels are designed exclusively for use with disc brakes. Do not use these wheels with rim brakes.
•
If the quick release lever is on the same side as the disc brake rotor, there is the danger that it may interfere with the disc
brake rotor. Make sure that, even if the quick release lever is tightened as much as possible by hand, the quick release
lever does not interfere with the disc brake rotor. If the lever interferes with the disc brake rotor, stop using the wheel
and consult a dealer or an agency.

CAUTION
Be sure to also inform users of the following:
•
Use rim tape which can withstand high pressure, otherwise the tires may suddenly puncture and come off, which may result in severe injury.
Furthermore, it is not recommended that you reuse rim tape after it has been removed from the wheel. If the tape is reused, the tires may suddenly
puncture and come off, and severe injury may result.
•
When you replace the rim tape, use the one that matches the rim size. If you use a rim tape that does not match the rim size, a sudden puncture may
occur, and you may fall off the bicycle.
•
The tires should be inflated to the pressure indicated on the tires before use.
•
When using a puncture repair agent, consult a dealer or an agency.
Burn-in period
•
Disc brakes have a burn-in period, and the braking force will gradually increase as the burn-in period progresses. Make sure that you are aware of any
such increases in braking force when using the brakes during the burn-in period. The same thing will happen when the brake pads or disc brake rotor
are replaced.

TO ENSURE SAFETY
NOTE
Be sure to also inform users of the following:
•
Do not lubricate the internal parts of the hub. Otherwise, grease will flow out.
•
It is recommended that you ask a bicycle dealer to adjust the spoke tensions if there is any deviation in the spokes and after the first 1,000km of
riding.
•
Do not use detergent or other chemicals when wiping the wheel, otherwise the sticker on the rim or the paint may come off.
•
Products are not guaranteed against natural wear and deterioration from normal use and aging.
•
For maximum performance we highly recommend Shimano lubricants and maintenance products.
For Installation to the Bicycle, and Maintenance:
•
When replacing the E-THRU Axle, make sure that the replacement E-THRU Axle is of the same model as the current E-THRU Axle attached to the
frame.
A different model may not be mounted properly onto the frame due to differences in axle length, screw size, housing diameter, etc.
•
Use of genuine Shimano spokes and nipples is strongly recommended. Otherwise, the area where the spokes fit into the hub body may become
damaged.
•
If the wheel becomes stiff and difficult to turn, lubricate it with grease.
•
SM-AX720 is designed for ROAD bicycles and therefore may not be used on other bicycle types.
•
For compatible reflectors and spoke protectors, check the specifications table (http://www.si.shimano.com).
The actual product may differ from the illustration because this manual is intended mainly to explain the procedures for using
the product.

Cautions on the use of tubeless tires
Cautions on the use of tubeless tires
To ensure safety, be sure to observe the following
WARNING
•
Read these instructions carefully, and keep them in a safe place for later reference.
CAUTION
•
Do not use rim tape if using an inner tube. Rim tape may make it difficult to remove and install the tire, and the tire or tube may become damaged or
the tires may suddenly puncture, causing the bicycle to fall over.
NOTE
•
The tires should always be installed and removed by hand. Never use tools such as tire levers. They can damage the air seal between the tires and the
rims and cause air to leak out.
•
Do not tighten the valve nut too much, otherwise the valve seal may become warped and air leaks may occur.
•
If the tires are difficult to fit, use tap water or soapy water to help them slide more easily.
•
Products are not guaranteed against natural wear and deterioration from normal use and aging.
Installing tubeless tire valves
(A)
Install the valve so that it faces as shown
in the illustration.
(A)
Valve nut
NOTE
When tightening the valve nut, check that the
valve does not turn together with the valve
nut.
Installing the tires

Cautions on the use of tubeless tires
2
(A)
Insert the bead on the other side of the
tire starting from the point opposite the
air valve.
(A)
Air valve
3
It will become more difficult to insert the
bead at the side of the air valve.
In such cases, lift up the bead by hand
starting from the opposite side of the
tire, and work your way around to the
location of the air valve.
4
Grip the tire with both hands as shown
in the illustration and insert the tire into
the rim.
5
Inflate with air to lock the beads of the
tires into the rim as shown in the
illustration.
After this, deflate the tire and check that
the bead is locked into the rim.
Re-inflate the tire to the standard air
pressure for use.
If the bead is not locked into the rim, the
bead may separate from the rim when
the tire is deflated.
Maximum pressure
800kPa/116psi
